I had resized my photo to 600X600, so I don't think it's my pic is too big... is it?

Just thought I'd let you know.

Hi,
Your first attempt to upload was a 2mb file so JanW is probably correct, you most likely just grabbed the wrong one when you tried to upload. I have deleted it and you should now be able to upload the one that was also in your upload folder that was the correct size. The large size blocks any further uploading until the entire upload folder is deleted.
